FASTENER. ron JAR-cLosunEs.

Be it-known thatI, J onnW L Mnnn'ry a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Fasteners for J ar- Closures, of which the following is a specification.

This invention relates to jarclosures and more particularly to a novel form of fastener therefor. a

The object of the invention is to provide a fastener of simple and inexpensiveconstruction capable of being readily applied to (an ordinary jar and bymeans of whichv the lid or closure thereof may be securely clamped in position over the mouth of thejar so as The invention further aims to provide a fastener, the locking bail of which is pivotally mounted on trunnions extended laterally from opposite sides of the jar and provided with depending offset ears whichserve to a receive the ends of the clamping tbail, thus dispensing with the usual ear-supporting wire around the neck of the jar andcon- .sequently reducing the cost of manufacture.

The invention further contemplates a two part fastener, the clamping and locking bails of which are stamped from sheet metahs the a clamping bail having its intermediate and terminalportions rolled into substantially cylindrical formfor engagement with the jar-closure and offset ears of the locking bail, respectively. a

A still further object of the invention isgenerally to improve this class of devices so ing bail'detached. i

as to increase their utility, durability and efficiency. 1 1

Fig. 2 is a side elevation thereof showing the locking bail in loweredor clamping position;

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved fastener forming the sub- .ject-matter of the present invention is apthe closure in Specification of Letters Patent. i I Patented, NOV. 18, Application filed January 4, 1919. Serial 1109269317. l

plicableto jars, bottles, cans and similar I containers and Way of illustration is shown applied to a glass fruit jar in which designates the bodyqof the"jar,"6 theneck and 7 the lid or closure. Molded or otherwise formed integral with the neck of the into substantially" semi-circular form and I having its opposite ends enlarged to form upstanding ears 11 pierced by transverse apertures 12 for the reception of the trun: nions 8 and on whichtheilocking bail is piv-' otally-y mounted for swinging movement;

The metal constituting the locking bail 10 is offset laterally immediately below the ears 11,2LS indicated at13,and thence extended downwardly to form depending ears 14 also provided with apertures 15, adapted to p receive the terminals of a: clamping bail, in+ dicatedrat 16. Theoppositeedges iofthe metal. at the intermediate portion of .the

looking bail lOare preferably bent or rolled laterally at 17 so as to reinforce and strengthen the bail and alsowto; present a smooth rounded surface for contact with the fingers of the operator when clamping the jar; a

The clampingbail 16 is also preferably formed of a single strip of flat metal, the op posite longitudinal edges of said strip at the ends thereof beingbent or rolled into substantially cylindrical shape, as indicatedat '18, to" form reinforced terminals, the ends of which are bent' inwardly to formlugs'19 position over the mouth of and strengthened by the provision of the and the apertures 15 moved to a position out.

of vertical alinement with the trunnions 8 thereby causing said ears to exert a downward clamping action on the bail 16 and force the lid 7 against the washer 23 and thus hermetically seal the mouth of the jar. It will be noted that the clamping band 16 is arranged at the center of the jar while the trunnions S are offset with respect thereto. Consequently, when the locking bail 17 is swung downwardly, the ears lat will be moved to a position at the rear of the trunnions 8 and thus lock the bails 16 and 17 against further movement- In order to release the lid or closure 7 it is merely necessary to exert a slight upward pressure on the locking bail 17 which will swing the cars 14 forwardly and upwardly thereby releasing the clamping bail 16 so that said clamping bail may be swung to one side of the jar and thus permit removal of the lid 01' closure. The offset or shoulder 13 is preferably disposed in alinement with the lower longitudinal edge of the locking bail 17 and serves to space the ears 14 a sufficient distance from the neck of the jar to accommodate the pivots or lugs 19 and thereby prevent the lugs from contacting with the wall of the jar when operating the fastener.

By making the locking bail 10 of spring Having thus described the invention, what is claimed as new is:

1. The combination with a container in cluding a closure, of a locking bail formed of a flat sheet of metal pivotally mounted on the container and having its pivoted ends provided with depending ears offset with respect thereto, and a clamping bail pivotally connected with said ears and adapted to bear against the closure when the looking bail is swung downwardly, the opposite longitudinal edges of the locking ball at the center thereof being rolled laterally to form a finger piece. I

2. The combination with a container including a closure, of trunnions extending laterally from the opposite sides of the con tainer beneath said closure and disposed at one side of the vertical axis of the container, a locking bail having upstanding ears journaled on the trunnions and provided with laterally offset portions terminating in depending ears, and a clamping bail pivotally connected with the depending ears.

3. The combination with a container having laterally extending trunnions and provided with a closure, of a locking bail pivotally mounted on the trunnions and provided with depending perforated ears, and a flat clamping bail having its opposite ends rolled to form cylindrical portions, the terminals of which are bent inwardly and passed through the perforations in the depending ears to form a pivotal connection between the locking bail and said clamping bail.

4:. The combination with a container having'laterally extending trunnions and provided with a closure having spaced locking lugs on the upper surface thereof, of a looking bail pivotally mounted on the trunnions and provided with depending perforated ears offset with respect thereto, and a clamping bail formed of a flat sheet of metal having its opposite longitudinal edges at the ends thereof rolled into substantially cylindrical form and thence bent laterally to form lugs fitting within the perforations in the depending ears, the opposite longitudinal edges of the metal constituting the clamping bail being rolled laterally at the center thereof to'forin a cylindrical portion adapted to fit between the locking lugs on the closure, there being reinforcing ribs formed in the clamping bail on opposite sides of the cylindrical portion thereof.

In testimony whereof I aflix my signature.
